ments in heel-assembling machines of the type shown in the pending application of E. L. Page #695,018, in which an endless carrier is provided which comprises a series of connected heel-holders on which the heels are successively built as the carrier is moved automatically from one position to the next, in connection with heel-clamping means which act to press the. cemented lifts together after they have been piled on the holder, so that the heel will be held under pressure until the cement becomes set, the heel being automatically discharged fromits holder as the latter approaches the position in which it was previously fil1ed;this operation being carried on continuously. WVith said prior device it is necessary to provide a -heelf0 rming device on each holder, in which the heel is built, and as it is, in practice, frequently necessary,-to build heels of diiferent styles, it is necessary with this machine, to provide a set of heel forms forieach style of heel which is to be built upon the machine. This not-only causes a large initial expense for the holders, but it also requires considerable time to change all the forming devices on the holders each time it is desired to make a heel of difierent shape.

The object of my invention is to provide the machine, above referred to, with a heelforming device, which is adapted and arranged to be held in position on'each holder, while the heel is being assembled thereon, until the heel has been clamped thereon, so that the lifts will not thereafter become misplaced, and which may then be moved out of engagement with the heel into assembling position over the next succeeding holder, so that the same heel-forming device will be used in shaping all heels which are formed, and so that when it is necessary to change the style or shape of heels which are to be built, it is only necessary to change one set of heel engaging parts, thereby saving expense and greatly increasing the production of the machine. I accomplish this object by the means shown in the accompanying draw1ng,f1 n whlch, r Figure 1 1s a side elevation of a heel-assembling machine provided with my invene tron. 'Flgs." 2 and 3 are detail plan views thereof showing the parts in different positions. Fig. 4 is a Simi'lar'viewin front el'evation. Fig. 5 is across Section'on line 55 of Fig. 4. Fig. 6 is a detail View of the connecting mechanism, Fig. 7 is a detail view ofthe releasing mechanism. 7

p In the drawings only asufiicient portion of the machine is shown 'to'illustrate my in vention and its application to the particular prior machine above'referred to.

The machine comprises two vertically disposed sid'e framesl and 2,in the inner sides 1 of which endless groovesl and 2' are provided, said grooves extending horizontally for a greater portion 'of the length of said frames and being semicircularly curved at the ends thereof. An endless carrier is provided, which comprises a series of holders in the form of rectangular plates3, said plates being connected together ,by short links 4, having projecting lugs 4' thereon which are arranged to travel inthe grooves 1, 2". Suitable driving means is provided, which preferably comprises a shaft 5, arranged at the center of the curve vof the groovesat one end of the side frames, and an arm 6, which is mounted to swing thereon, said arm having a pawl 7 at its end whichis adapted to p engage lugs 0r teeth 8 on the inner side of the plates 3, said arm 6 being swung by any suitable power driven means, which may inelude a connecting'rod 9. The arrangement is such that the pawl 7 will be held in position to engage one of the lugs 8 when the arm 6 is in an approximately vertical positron, so that, when the-arm 6' is swung forwardly said carrier will be moved along in v Y the grooves, the distance which it is moved being arranged to correspond to the distance from the center of one plateto the center of the next.

Each holder plate vertically disposed breast-gage 10, which is arranged in the rear of the middleportion thereo-fwhich is adapted to receive the heels which are to be built thereon, said gagebe:

ing of suflicient he ght to cor p nd to the 3 is provided with a height-of any heel which is to be built on the machine. Clamping means for each holder plate 3-is provided, said means preferably comprising a presser plate 11, which is carried on the end of a stem 12, said stem being adjustably mounted in the end of an arm 13 at right angles thereto. Each arm 13 is mounted on a rod 1 1, and is arranged to swing in planes parallel to the surface of the particular holder plate 3 in which it is mounted, each rod 14 being mounted perpendicularly in its corresponding plate 3, in the rear of its breast-gage 10, and being adapted to slide therein to raise and lower the plate 11. i A spring 15 is mounted on the lower end of each rod 14, between the under side of the plate 3, and a head 14 on the lower or inner end of the rod, so as to draw said plate 11 inwardly. A rib 2 is formed on the inner side of the rear frame 2 in position to engage said head 1%, so that, .when a holder plate 3 reaches a certain position, said head 14; will be carried into engagement with said rib 2 which will force said rod 14 outward, so that the plate 11 may be moved out of clamping position, and swung aside to permit the heel which was clamped to fall from the holder, and another heel to be assembled therein;

A carriage 16 is slidably mounted 011 a pair of horizontal guide-rods 17 secured on the front side of the frame 1, and two supports 18 and 19, are connected to the upper end thereof and extend horizontally over the carrier, or series of connected holder plates 3, the support 18 being rigidly connected to the carriage 16, and the support 19 i being pivotally connected thereto by means of a pivot bolt 20, which is arranged in front of'the carriage .16. A spring 30 connects said supports 18 and 19 and normally holds the latter in the position of Fig. 3.

A pair of fingers 21 are respectively mounted to slide on the supports 18 and 19, When the support 19 is in its normal position, shown in Fig. 3, said grooves extend convergently toward the breast-gage '10, said fingers 21 being held in position by bolts 23 which pass through slots therein and springs 24 being interposed between the front ends of said slots and said bolts 23, so that said springs tend normally to push said fingers for- Wardly, and hold the rear ends of said slots against said bolts. Heel-formers 25 are detachably connected to the ends of said fingers 21, the heel engaging faces thereof be ing arranged to correspond to the curved rear portions of the heel at each side of the middle line thereof, the arrangement being such that when a heel is supported on a plate 3 with its breast portion arranged in engagement with the breast-gage 10, the heel-formers 25 will bear against the curved rear side portions of the heel at equal disstances from, and at opposite sides of its middle line. Vith this arrangement, when the lifts are placed in the space between said formers and the breast-gage, they will be pushed into the desired position, the springs 2 1 merely yielding when necessary to permit the lifts to become properly arranged, or to accommodate over-sized lifts.

A bell-crank lever 31, having vertically and horizontallydisposed arms, is mounted on a pivot 32 in the carriage 16, and the horizontal arm has an upwardly extending lug 31, at its end which is adapted to engage the outer edge of the support 19, and lock the same in the position of Fig. 1. A bell-crank lever is mounted on a pivot 34c in the carriage 16, at the left-hand end thereof,,and has a depending lug 33 at one end, which is adapted by its gravity, to enter any one of the apertures 35 with which'each holder plate 3 is provided. An unlocking bar is slidably mounted on the front side of the carriage 16, and is provided with a laterally projecting arm 37 and an inclined end face 36. A lug 38 is formed on the opposite end of lever 33 from its end bearing lug 33, which is arranged to be engaged by said face 36, and the arm 37 is provided with an inwardly projecting lug 37 arranged to engage the depending arm of lever 31.

A spring 39 is attached to the carriage 16 and normally holds the same in position opposite the middle of the position in which each holder plate is held when the heel lifts are placed therein, which I will hereafter term the initial position, and a spring -10 is attached to the depending arm of lever 31 and normally holds the same in the position of Fig. 41-.

The operation of the device is as follows :The parts being'in the position of Figs. 1, 3, 4 and 5, the heel is built by placing the cemented lifts therein, in the usual manner. When the heel has been assembled in the form, the driving mechanism is operated and, asthe carrier is moved, a projection 41 on frame 2, strikes on a lug 12 on arm 13, and throws the Inesser-plate 11 into clamping position over the heel. The head. 14 of bolt 14: then moves out of engagement with rib 2, so that the clamping-plate 11 is moved into clamping engagement with the heel. The carriage 16 is then I 33' out of the aperture 35, and unlocking riage 16 is unlocked from the holder plate 3. The result is, that, as soon as the carriage 16 is unlocked, the spring 89 will draw back said carriage to the initial position, the support 19 being then free to swing away from the heel, so that the former 25, which it carries, will pass the heel, as shown in Fig. 2. By this time the carrier will have reached the next initial position, and, as the carriage moves opposite the next plate, the lug 31 will fall into its aperture 35, locking the carriage thereto, and, as soon as the former 25 clears the heel, as above described, the spring 30 will return the support 19 to its normal position, and

the spring 410 will then return the lever 31' to its normal position, to lock the support 19. The above described operation may then be repeated.

With the above described device, when it is desired to build a heel of difierent form from that for which the formers 25 are adapted, it is merely necessary to remove said formers and replace them with others of the desired shape, the breast-gage 10 be ing adapted for all shapes. The expense of adapting the machine to difierently shaped heels is therefore very small and but little I time is required to make the change.

It will be observed that a prime essential to the above described mechanism is the holding of the forming devices in forming position until the heel is pressed firmly on the holder plate, so that the lifts will not become displaced, after which the forming devices may be disengaged from the heel, so that the holder may be moved on, and the forming devices be returned to their initial positions. The particular manner in which this result is accomplished is of secondary importance.
